CubeSurfer Replacement for 2.8?
I found it in case you still need it. You can download a zip from the GitHub page at https://github.com/porkminer/CubeSurfer, but it gives you an error when you try to istall it in Blender. I fixed it by changing the line from cubesurfer import mciso just to import mciso. The download link is https://gofile.io/?c=sEWqb3.
